Specification of Letters Patent. Patented S t 28 1920 Application filedApril 6, 1914. Serial No. 829,866.

To all whom it may concern:

7 Be it known that I, EDWARD W. BURGESS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Silo-Packers, of whichthe following is a full, clear, and exact specification. v

My invention relatesto silos, and in particular to V mechanism forautomatically packing the material as it is delivered to the silo. Theoperation of packing the si lage in the silo hashei'etofore beenaccomplished by placing two or moremen within the silo and tramping thesilage as it was delivered thereto. This operation was an extremelydisagreeableand arduous one and much loss of silage resulted frominsufiicient packing. The object of this invention is to provide amechanism which will automatically and effectively pack the material,and one adjustable to silos having different diameters and not requiringany contact with the body .of the silo to permit the operation of themechanism. The invention consists in certain novel features ofconstruction, combination and arrangement of parts, as will be morefully described and particularly pointed out in the appended claims.

.In the drawings Figure lis a top plan View of a packer having myinvention embodied in its construction;

Fig. 2is a side elevation of Fig. 1;

Fig. 3 is a vertical section of a silo designed toillustrate the mannerof operating the packing mechanism;

Fig. 4 is a cross section of Fig. 1 on an B; and Fig. 5 is a crosssection of Fig. 1 on an enlarged scale and along. CD.-

;Referring to the drawings, wherein the same reference numeralsdesignate like parts throughout the several views, a common form ofcircular silo is represented by 1,,and it may be of metal, wood, cementor other construction, having substantially smooth and symmetricalinside walls, 2 represents the packer, including two U- shaped'sections3, alike in form and having slotted inner ends that overlap each otherat'the 'middle of the packer, whereby the 'pa'cker is adjustable iniength to meet the requirements of operation in silos having mountedupon one of the vertically disposed arms of the yoke and adapted toengage with a toothed flange 11 integral with the winding drum in amanner to secure the drum against rotation in one direction, the yokebeing permitted to turn freely about the thimble section 6 when thepacker is rotated during'its operation. 12 represents verticallydisposed shafts journaled in bearing members 13 secured to the outsideends of the packer sections 3, the shafts being provided with laterallyextending arms 14: at opposite ends thereof, and preferably integraltherewith, upon which are journaled guide wheels 15 adapted to roll uponthe adjacent wall of the silo as the packer rises and falls, in itsoperation. 16 represents torsional springs carried by the shafts 12 andoperative between a fixed part of the packer sections and one of thearms 14 in a manner to yieldingly hold the guide wheels 15 in engagementwith the wall of the silo and permit them to accommodate themselves toany irregular contour of the sur-' face of the wall. 17 representssectors, prefera ly made of wood, and secured to the bottom members ofthe packer sections 3 by means of strap members 18,,upon the oppositesides ofthe longitudinal center of the packer, and 19 represents bracemembers having their lower ends secured to the and 26 a pin carried'bythe pulley and engaging with the arm during halfa revolution ofthepulley, and to permit the arm to'swing' about its axis independentofthe pin during the remaining half of the revolution of the pulley inawell-known way. '27 represents a tension spring having one end securedtothe free end of the arm and its opposite end to one end of a hoist Inoperation the dimensions of the packer are such as will readily permitit to be passed through the door opening in the wall of the silo. Thesections are then adjusted longitudinally so that the packer may bevmoved freely up or downalong thewalls of the silo and rotated'therein.Thehoisting rope is adjusted upon the winding drum in a mannerpermitting the packer to descend to the desired plane, and when motionis-imparted to the pulley 23tl1earm 25. alternately pulls down upon thehoisting rope and releases it in a manner to liftith'e packer a"predetermined height and permit ity to descend by gravity upon thematerial in a step by step rotative movement, and the operator adjuststhe winding drum to take up the slack in the hoisting rope and as thesilo is gradually filled. I

Having shown one embodiment of my invention in its preferred form, it isunderstood that various changes in form, proportions and manner ofoperation may bemade without departing from the principle or spirit ofthe invention.

What I claim as my invention, and desire to secure by Letters Patent,is:

1. A silo packer adapted to have-arising and, falling movement within asilo, and

'7 means whereby the packer may be slidably adjusted for use in siloshaving different diameters. j 1 'f ;"2. A silo packer having sectionsand adapted to have a rising and falling anda rotative movement withinthe walls of the silo, and means whereby the packer sections may beslidably adjusted upon-each other toadapt said packer for use in siloshaving diil'erent diameters.

3. A silo packer adapted to have a rising and falling movement withinthe walls of the silo, said packer including diametrically disposedU-sh'aped sections having their inner ends overlapping each other andadjustably secured together whereby the packer may be extended orcontracted lon- 'gitudinally. v

4. A silo packer and falling movement within the walls of the silo, saidpacker including a .pair of diametrically disposed U-shaped sectionshaving their innerends slotted'longitudiabout the axis of said bolt.

adapted to have a rising said sections and clamping the two sections 111ad usted relation.

5. A silo packer adapted to have a rising and falling movement withinthewalls of' the silo, said packer including a pair of diametricallydisposed sections adjustable longitudinally upon each other, anda'winding drum swivelly connected with said packer at its middle. 1

6; A silo packer adapted to have a rising and falling movement withinthe walls of j the silo, said packer including a pair of diametricallydisposed U shaped sections'ha'ving their. innerends overlappingand'a'djustable longitudinally upon each other, spacing pipes disposedbetween theinner ends'of said sections, a yoke'member having a windingdrum movable therein, a through bolt received by an opening in said yokeand" said'spacing pipeand securing said packer sections in adjustedrelation, said yoke being. permitted to turn freely 7 A'silo-packerhaving packing members and'adapted to havefa rising and a fallingmovement within the walls of the silo, and guide members carried by andmovable with said packing -menibers*and adapted to engage with the wallsof the silo. 1
